The purpose of the study was to find out the effect of land and shallow water aerobic exercise on cardio vascular fitness among school students. To attain the purpose, Sixty (N=60) school students were selected as subject at random. They were divided equally into three group of twenty (n=20) each namely Land Based Aerobic Exercises group, Water Based Aerobic Exercises group and control group. The experimental group underwent their respective training for three days per week for 12 weeks duration. Cardiovascular fitness only selected for this study and it was assessed through 12 minutes run/walk test. To find out the difference between pre and post test mean values Independent‘t’ test was followed. The results of the study showed significant differences (0.05 Level) in cardiovascular endurance, among the groups. Land Based Aerobic Exercises are superior than Water Based Aerobic Exercise in Cardiovascular endurance. The present study demonstrated that differences in cardiovascular endurance, among Land and Shallow Water Aerobic Exercise and Control group. Land Aerobic Exercise may have potential role of increasing cardiovascular endurance.
